To all whom it may concern:

Be it known that I, WILLIAM B. VANSIZE, a citizen of the United States,residing in Brooklyn, in the city of New York county of Kings, State ofNew York, have invented certain new and useful Improvements in RecordingCorrelated Light and Sound Effects, of which the following is aspecification.

This application is a division of my application Serial No. 36,938,filed June 29, 1915.

This ,inventionrelates to recording light and sound efiects which arecorrelated in time and significance, and the object of the invention isto record, in moving-picture form, as on a film, photographically,certain moving objects or individuals, and at the same time record on asound-record medium any intelligible sounds, whether purely vocal orpurely musical, or both, due to said objects. This is done by placing oneach moving object independent means for transmitting sound through thenatural medium, or Hertzian waves, thus making each object absolutelyindependent of circuit connections or contacts, with respect to fixedpoints or circuits. The apparatus employed includes telephonic wirelesstransmitting and recording devices, and the means employed for recordingthe sound is preferably a wire of hardened magnetic metal, like steel,of small diameter; this wire is magnetized by the free, pole of anelectro-magnet, the coil of which magnet is subjected toelectro-magnetic waves transmitted through the natural medium; bynatural medium is meant the ether surrounding the earth, which Hertzdemonstrated to be a natural medium subject toelectro-magneticinfluences, and it is here intended to inc ude all the various means bywhich wireless signaling is and has been accomplished. T o produce theseelectro-mag-- netic Waves, each object photographed, and

emitting sounds, is equipped with a portable telephonic wirelesstransmitting apparatus. By this it is meant to include a generator ofhigh frequency oscillations, and a means for inflecting the oscillationswith variations due to sound waves, like a telephone transmitter of themicrophone species. It is preferable to employ, as a part of thisapparatus, a vacuum valve adapted for transmit ting high frequencyoscillations; this valve, in addition to the usual hot element and coldelement, preferably has a third element adapted to form the terminal ofa circuit and influence or control the electrical condition of the spacebetween the two said elements; this may be like a grid, located withinthe vacuum between the hot element and the cold element; also there is abattery having an electro-motive forceof about one hundred volts, eachcell is of diminutive form and light Weight, of the Plant or Faure type,and fifty such cells, arranged in series, should supply about onehundred volts; these cells are connected between the hot element and thecold element; the telephone transmitter is included in or associatedwith the radiating circuit and supported upon the chest of the object orindividual. There is a battery for heating the filament in the vacuum,and when this battery is adjusted to produce a certain degree of heatand the battery and the circuit connecting the hot and cold element istuned and so adjusted as to cause the valve to oscillate, the variationof voice waves or sound waves due to the microphone transmitter willinflect the resulting oscillatory discharge, and as these oscillationsare radiated, there results a corresponding wave motion in the ether, aswell recorder is connected in circuit with a vacuum detector or valve,as above described, adjusted for the reception and detection ofoscillations, and the valve is associated with the receiving antenna.The antenna at the transmitting station or object, if used, is,preferably, in the form of a wire of practically invisible dimensionsand color, and projects a foot or two above the object. The lower end ofthis antenna terminates in contacts and these contacts are adapted toengage a sheet-metal floor or capacity. These contacts are preferablyplaced in the soles of the shoes of the individual. The picture recordand the sound-record medium or wire are advanced at a predeterminedrate, and the two records are made simultaneously, in the identicalcorrelation fective use of Hertzian oscillations, a reit i 1,219,682

ceiving and repeating station is preferably received, at this station,by a valve detector,

such as has been described; A wire circuit, preferably acomplete'metallic circuit, is eX- tended back to the point Where thesound record, in close proximity to the picture rec- 0rd, is to be made.The valve detector is preferably connected as a form or species ofrepeater or relay between this last-named circuit and the radioreceiving circuit. This separated station is used so as to provide forchanges in position and movement by the moving object, the extent ofmovement, ordinarily, of the object being but a small part of the entiredistance separating the object from the receiving station. If thisprovision werenot made, re-tuning or re-adjustment of the apparatuscarried by the objectv or individual, as said object moves about, wouldbe necessary at frequent intervals.

The accompanying drawings illustrate the invention. 7

Figure 1 shows apparatus employed in recording the movemnt andvocalization of two objects or individuals 0I1 a stage. Fig. 2 shows, indotted outline and detail, the transmitting apparatus carried by eachindividual.

Tn Fig. 1 the movements iittera nces of twoobjects or individuals, 15,and 16, are

shown on a stage this stage has a metal or conducting surface or floor,17, connected to earth as shown at 25. Each object, 15, 16, may beprovided with awire or antenna, 18, projecting slightly above the head";This is formed of small-gage Wire and givena color which will notphotograph efl'ectively, the object being to avoid its representation inthe picture; the antenna,- 18, is connected in the circuit, 19,containing an inductance, 32, utilized as the secondary of aninductioncoil in series with a microphone or current varying telephonetransmitter, 20, carried on the chest of the individual, so that chestvibrations are eflective to control the telephonic transmission bytransmitter 20. The wire 19 is bifurcated and continued in twodivisions, 21 and 22, to contaets, 23 and 24, placed in the bottom ofthe shoe of the individual, so as to makecontact with the metal floor,17. Tn addition to the circuits described, there is carried by theindividual a vacuum valve, 26, having a hot element, 27,

and a cold element, 28, with an intermediate grid, 29; the hot element27 is heated by a small dry battery, 35. A battery, 33, of, say, fiftysecondary elements of small size and weight, preferably one or twoounces per cell, is connected in circuit between the cold element 28 andthe hot element 27. Tn

this circuit is an inductance, 31, employed as the primary of aninduction coil, and inductively associated with the secondary, 32. Thethird or grid element, 29,- is in circuit with six cells of battery, 34,connected. to the hot element, and including an inductance, 30,inductively associated with the coil, 31. The inductance 30 isadjustable and, when properly adjusted, the local circuits described,including the valve, constitute a generator of high-frequencyoscillations. On the stage, I have shown a tripod supporting a camera,with a crank handle, 13; this crank 13, when rotated clockwise, advancesthe transparent film of sensitized surface upon which the photographicrecord is made, as is well' known. The camera is shown at 12. Thesound-record medium is a tape of steel or a steel wire, like pianostringWire, shown at 10. A supply of this wire is carried on a spool andpasses around a series of pulleys, including a grooved pulley, 14, onshaft with .crank.13, so that When the film is advanced by turning thecrank 13 the sound-record medium 10 is advanced with it or inpredetermined relation, as may one-quarterto one-half" wave lengthdistant from the. stage 17 there is erected any well known form ofwireless antenna, 40; included in its circuit is an adjustablecondenser, 41, aninductance, 42, of adjustable character, and a groundconnection, 43. Tnductance 42 is employed as the primary of aninductorium, the secondary of which, in

inductance form, is shown at ,44, in circuit with a battery, 45, in acircuit one terminal of which is connected to the grid, 53; the other.terminal is connected to the hot element 56 at 54', 55. The battery forheating the element 56 is shown at 46, and a variable resistance, 47,with an adjustable contact, 48, provides for adjusting the heatingcapacity of the battery and the heat of the filament 56. Tt is to benoted that the sounds emitted by the objects 15 and 16 aretelephonically transmitted, -.by means of the microphone-transmitter 20,and the highfrequency generator carried upon the person, as shown inFig. 2, by radio-signals or Hertzian waves, tothe antenna 40, and arerepeated back to the valve and the metallic circuit 51, 52, to thesound-recording magnet 11, where the sounds are recorded on the wire 10,while a visible record'is photographically made upon the him of thecamera 12 in correlated order.

All batteries shown in connection with the vacuum valves are to beadjustable as regardslelectro-inotive force.

It is intended to include in the term natural medium used in the claims,the space separating the. transmitting and recording station only and-Hertzian waves and any magnetic or electro-magnetic waves, or influenceof an intangible nature, operating through said space, and where wire ormaterial of a conducting nature does not form a complete circuit.
